Denver Zoo is expecting a baby sloth in January or late February

Grab your champagne: The Denver Zoo announced Wednesday that it is expecting a baby sloth.

The sloth will be the first offspring of Charlotte and Elliot, who were matched as part of the Species Survival Plan, said zoo spokeswoman Marina Belisle.

Sloths have a 10-month gestation period, she said. Zookeepers believe Charlotte, who is a Linne's two-toed sloth, is between 7 months and 10 months pregnant, meaning the baby could arrive anytime now through late February.
